PowerPC 440 tlbre instruction (Re: PowerPC 440 mbar and tlbwe instructions)

[UMENO Takashi]

Hello, folks!

I think tlbre instruction may have three operands 
when specify PPC440 or PPC405.

When I specify PPC405, GNU assembler exit without no errors,
but when I specify PPC405, GNU assembler exit with one error.

So, I think GNU assembler has some bugs when specify PPC440 processor.

% cat -n test00.s
     1          .globl  Nop
     2  Nop:
     3          tlbwe   %r0,%r1,0
     4          tlbre   %r0,%r1,0
     5          blr
% as -m405 test00.s
% as -m440 test00.s
